US and Greek scientists studying a 2,400-year-old shipwreck in the Aegean Sea did a DNA analysis of an earthen jar they had found and discovered that it contained ... salad dressing!

Genetic analysis has revealed the contents of an ancient shipwreck dating back to the era of the Roman Republic and Athenian Empire. The cargo was olive oil flavored with oregano.

Beyond discovering ingredients for Italian salad dressing on the sea floor, such research could provide a wealth of insights concerning the everyday life of ancient seafaring civilizations that would otherwise be lost at sea.

I honestly thought this was going to be that "Sinko da Mayo" joke that circulated the internet a while back.

Here's the joke, if you've never come across it. I don't wish to offend or annoy, just to entertain. :]

Most people don't know that back in 1912, Hellmann's mayonnaise was manufactured in England. In fact, the Titanic was carrying 12,000 jars of the condiment scheduled for delivery in Vera Cruz, Mexico, which was to be the next port of call for the great ship after its stop in New York. This would have been the largest single shipment of mayonnaise ever delivered to Mexico. But as we know, the great ship did not make it to New York. The ship hit an iceberg and sank, and the cargo was forever lost. The people of Mexico, who were crazy about mayonnaise, and were eagerly awaiting its delivery, were disconsolate at the loss. Their anguish was so great, that they declared a National Day of Mourning, which they still observe to this day. The National Day of Mourning occurs each year on May 5th and is known, of course, as Sinko de Mayo.
